Blackberry shares plunge more than 20% on outlook cut, revenue miss.

DOWN 22%

Blackberry Ltd. missed quarterly revenue estimates and cut the top end of its full-year forecast on Tuesday, hurt by weakness in sales of enterprise software, sending its shares down more than 20 per cent to near four-year lows.

Once known for its smartphones before losing out to Apple Inc.’s iphones and Google-powered Android devices, Blackberry now sells security software such as those used by corporations and government agencies.

The company is also focusing on software used in emerging areas like driverless cars.

Adjusted revenue from Blackberry’s Internet of Things business, which includes the technology solutions and enterprise software and services ( ESS) units, fell five per cent to US$ 134 million, missing estimates for the secondstraight quarter.

Analysts on average had expected revenue of US$150 million from the business.

The technology solutions segment, which houses QNX — a software used by carmakers to provide infotainment and other services to customers — continued to perform well with double- digit growth, but there was softness in the ESS business, chief executive John Chen said on a post-earnings call.

Raymond James analysts estimated a revenue fall of 15 per cent to 17 per cent in the enterprise software segment.

“I would say that the weakness of ESS is really on execution,” Chen said, attributing it to changes in its sales team.

The company said it now expects current-year revenue to rise between 23 per cent and 25 per cent, compared to its earlier forecast of 23 per cent to 27 per cent.

In response to a question from an analyst about competition, Chen said the company saw Microsoft Corp. being “a little bit more aggressive.”

Waterloo, Ont .- based Blackberry posted a net loss of US$ 44 million in the second quarter ended Aug. 31, compared with a profit of US$ 43 million a year earlier, as it invested heavily to integrate recently acquired Cylance.

In February, the company bought the California- based cybersecurity firm, whose software uses machine learning to pre- empt security breaches.

Blackberry’s operating expenses rose nearly 80 per cent to US$219 million in the quarter.

On a per- share adjusted basis, the company broke even, in line with analysts’ expectations.

Adjusted revenue rose about 22 per cent to US$261 million, missing estimates of US$ 266 million, according to IBES data from Refinitiv.

Blackberry’s U. S.- listed shares closed at US$ 5.82 in New York, down 22.5 per cent, and the Toronto stock ended the day at $7.75, down 22 per cent.
